X86: Emit logical shift by constant splat of <16 x i8> as a <8 x i16> shift and zero out the bits where zeros should've been shifted in.

-mlink-bitcode-file flag), and more generally llvm::Modules, before
running optimisations.

Fix return type for X86 mpsadbw instrinsic. The instruction takes in a vector of 8-bit integers, but produces a vector of 16-bit integers.

Fix pr11266.

On x86: (shl V, 1) -> add V,V

Hardware support for vector-shift is sparse and in many cases we scalarize the
result. Additionally, on sandybridge padd is faster than shl.

The integrated assembler seems to be working pretty well for -static code
now, so remove the hacks to disable it.

Do a relative path ln command instead of an absolute path one. Some people strangely enough have different directory layouts...

integer-cast pointer value.

just integers and floating point types. Since we don't support evaluating class
types or performing lvalue-to-rvalue conversions on array elements yet, this
just means pointer types right now.

If all of the inputs are zero/any_extended, create a new simple BV
which can be further optimized by other BV optimizations.

Track the function invocation where an lvalue referring to a constexpr function
parameter originated from, and use it to substitute the correct argument and to
determine whether such an argument's lifetime has ended.

ClangExpressionDeclMap to ClangASTSource, and
moved all general type and namespace lookups
into ClangASTSource.  Now ClangASTSource is ready
to complete types given nothing more than a target
and an AST context.

SimplifyLibCalls: Use IRBuilder.CreateGlobalString when creating a string for printf->puts, which correctly sets the unnamed_addr bit on the resulting GlobalVariable.

AST importer on completing namespace mappings from
ClangExpressionDeclMap to ClangASTSource.

ClangASTSource now contains a TargetSP which it
uses to lookup namespaces in all of a target's
modules.  I will use the TargetSP in the future to
look up globals.

command suffix:

(lldb) expression/x 3+3

Since "expression" is a raw command that has options, we need to make sure the
command gets its options properly terminated with a "--".

Also fixed an issue where if you try to use the GDB command suffix on a 
command that doesn't support the "--gdb-format" command, it will report an
appropriate error.

For the fix above, you can query an lldb_private::Options object to see if it
supports a long option by name.

implicitly perform an lvalue-to-rvalue conversion if used on an lvalue

of them will accept expressions with side-effects.

This also helps break the infinite loop caused when target is null.

So that we can have:
